Entanglement Dynamics of Detectors in an Einstein Cylinder
Shih-Yuin Lin, Chung-Hsien Chou, Bei-Lok Hu
We investigate how nontrivial topology affects the entanglement dynamics between a detector and a quantum field and between two detectors mediated by a quantum field. Nontrivial to…
Quantum teleportation between moving detectors
Shih-Yuin Lin, Chung-Hsien Chou, B. L. Hu
It is commonly believed that the fidelity of quantum teleportation using localized quantum objects with one party or both accelerated in vacuum would be degraded due to the heat-up…
Quantum teleportation between moving detectors in a quantum field
Shih-Yuin Lin, Kazutomu Shiokawa, Chung-Hsien Chou +1
We consider the quantum teleportation of continuous variables modeled by Unruh-DeWitt detectors coupled to a common quantum field initially in the Minkowski vacuum. An unknown cohe…
Quantum entanglement and entropy in particle creation
Shih-Yuin Lin, Chung-Hsien Chou, B. L. Hu
We investigate the basic theoretical issues in the quantum entanglement of particle pairs created from the vacuum in a time-dependent background field or spacetime. Similar to entr…
Disentanglement of two harmonic oscillators in relativistic motion
Shih-Yuin Lin, Chung-Hsien Chou, B. L. Hu
We study the dynamics of quantum entanglement between two Unruh-DeWitt detectors, one stationary (Alice), and another uniformly accelerating (Rob), with no direct interaction but c…
Black holes and Rindler superspace: classical singularity and quantum unitarity
Chung-Hsien Chou, Chopin Soo, Hoi-Lai Yu
Canonical quantization of spherically symmetric initial data which is appropriate to classical interior black hole solutions in four dimensions is carried out and solved exactly wi…
Effective gauge group of pure loop quantum gravity is SO(3): New estimate of the Immirzi parameter
Chung-Hsien Chou, Yi Ling, Chopin Soo +1
We argue that the effective gauge group for {\it pure} four-dimensional loop quantum gravity(LQG) is SO(3) (or ) instead of SU(2) (or ). As a result, links with h…
Origin of the Immirzi Parameter
Chung-Hsien Chou, Roh-Suan Tung, Hoi-Lai Yu
Using quadratic spinor techniques we demonstrate that the Immirzi parameter can be expressed as ratio between scalar and pseudo-scalar contributions in the theory and can be interp…
